/* May 23, 2002 Initial Notes:
*
* I'm still tweaking this stuff, but it passes the tests I've thrown
* at it, and Erik needs it for the gcc port. The glibc extension
* __wcsnrtombs() hasn't been tested, as I didn't find a test for it
* in the glibc source. I also need to fix the behavior of
* _wchar_utf8sntowcs() if the max number of wchars to convert is 0.
*
* UTF-8 -> wchar -> UTF-8 conversion tests on Markus Kuhn's UTF-8-demo.txt
* file on my platform (x86) show about 5-10% faster conversion speed than
* glibc with mbsrtowcs()/wcsrtombs() and almost twice as fast as glibc with
* individual mbrtowc()/wcrtomb() calls.
*
* If 'DECODER' is defined, then _wchar_utf8sntowcs() will be compiled
* as a fail-safe UTF-8 decoder appropriate for a terminal, etc. which
